7.3.1

Forum Display Options / Default Topics Per Page: 15

Now, I'm assuming that when you click on any given forum - you'll get a list of topics. I only ever see ten.

Or am I misunderstanding this function?

Oops - just found this.

But I still don't understand why a query is needed.
The setting in the CP doesn't say it's for individual forums.
Is this a bug?
